  • Publication number: 20190123005
    Abstract: The present disclosure relates generally to flip chip technology and more particularly, to a method for fabricating a mechanically anchored controlled collapse chip connection (C4) pad on a semiconductor structure and a structure formed thereby. In an embodiment, a method is disclosed that includes forming a C4 pad on a patterned dielectric layer having grooves therein, the grooves providing an interfacial surface area between the patterned dielectric layer and the C4 pad sufficient to inhibit the C4 pad from delaminating during thermal expansion or contraction.

  • Publication number: 20190121912
    Abstract: The present disclosure is directed to systems and methods for providing dynamic communication threads in response to a detected interaction with a sponsored digital content item. For example, systems and method described herein detect a user interaction with a sponsored digital content item and generate a screened communication thread between the user and the sponsor that is not available to the sponsor. The screened communication thread serves as a reminder to the user of the sponsored digital content item. Systems and methods described herein convert the screened communication thread to an open communication thread based on user interaction with the screened communication thread (e.g., after the user submits a reply in the screened communication thread). Thus, systems and methods described herein protect the user's online privacy unless and until the user indicates a desire to interact with the sponsor.

  • Patent number: 10229875
    Abstract: A back end of the line (BEOL) fuse structure having a stack of vias. The stacking of vias leads to high aspect ratios making liner and seed coverage inside the vias poorer. The weakness of the liner and seed layers leads to a higher probability of electromigration (EM) failure. The fuse structure addresses failures due to poor liner and seed coverage. Design features permit determining where failures occur, determining the extent of the damaged region after fuse programming and preventing further propagation of the damaged dielectric region.

  • Patent number: 10224238
    Abstract: A component such as a display may have a substrate and thin-film circuitry on the substrate. The thin-film circuitry may be used to form an array of pixels for a display or other circuit structures. Metal traces may be formed among dielectric layers in the thin-film circuitry. Metal traces may be provided with insulating protective sidewall structures. The protective sidewall structures may be formed by treating exposed edge surfaces of the metal traces. A metal trace may have multiple layers such as a core metal layer sandwiched between barrier metal layers. The core metal layer may be formed from a metal that is subject to corrosion. The protective sidewall structures may help prevent corrosion in the core metal layer. Surface treatments such as oxidation, nitridation, and other processes may be used in forming the protective sidewall structures.

  • Publication number: 20190008898
    Abstract: The present invention provides compositions and methods for inhibiting one or more diacylglycerol kinase (DGK) isoform in a cell in order to enhance the cytolytic activity of the cell. In one embodiment, the cells may be used in adoptive T cell transfer. For example, in some embodiments, the cell is modified to express a chimeric antigen receptor (CAR). Inhibition of DGK in T cells used in adoptive T cell transfer increases cytolytic activity of the T cells and thus may be used in the treatment of a variety of conditions, including cancer, infection, and immune disorders.

  • Publication number: 20180368082
    Abstract: Disclosed aspects relate to methods and apparatus for coexistent radio frequency (RF) systems in a wireless device. Control of a wireless device includes detecting when a turn on signal is issued to a first radio system, and then controlling the second radio system to either modify the operation of receiver circuitry in the second radio system to protect components within that system, or modify transmit circuitry to stop transmissions for protecting components within one radio system potentially affected by transmission from the other radio system in the wireless device. Disclosed also is monitoring of transmission states of the radio systems based on reading messages between the first and second radio systems and issuing a notification message based thereon such that one of the radio systems may suspend monitoring of a transmit channel for permission to transmit in order to reduce power consumption due to such monitoring of the channel.
